That's very good mileage. In my 08 Fit sport I currently have an average of something like 36. This summer (from 0-4000 miles on the car) I was averaging 37.6. I've broken 40 only once, but my goal is to average >39 on at least 4 fills before I'll be happy. Recently it's been pretty cold (-8 to 20) and my last fill I got 34, so I was pretty happy with that because the weather was so poor.
I can't wait until summer when I'll be getting better mileage to see if I can break and stay at or above the 39 mpg mark.!
